the “W” word. Last weekend we moved ashore, this weekend it was water systems and A/C winterizing. Ran the water out of the tank, then blue air through the lines, Water Heater was bypassed. I am a bit anal so after lines were blown out, I o pumped pink stuff through the lines. Added 10 gallons to the water tank and ran that through. Water heater was just blown out as lots of room for anything left to expand. A/C ….well I was tired of disconnecting hoses and trying to flush with fresh water and then get pink through iit. SO, I used a 3 way ball valve and made a type of winterizing system. On one side, water flows through teh valve to the A/C pump. On other side of valve, I put a garden hose adaptor and used a washing machine hose to run fresh water through the system. NO need to run the pump. Then filled a bucket with pink, and put hose in the bucket, turned on the A/C’s and the pump sucked the pink through the lines. Used less and also no hassles disconnecting hoses and trying to keep the pump primed. i was in that bilge for longest ever 1.5 hours. I was going to do same to genset, but just didn’t have it in me. So strainer cover off, and started genset and kept strainer full with hose. Then was able to keep pouring pink and then -60 through. Overkill but used 6 gallons. The A/C new way is a better way. However, NEXT year for that one!
